Best Answer

a broken valve spring could be the cause, or a lifter. Start by checking the compression for the number 8 cylinder, then remove the valve cover to inspect the rockers and lifters.

How do you stop detonation?

Detonation, also referred to as knocking in gasoline engines happens when the gasoline vapor in the cylinder ignites prematurely before the piston is in an optimum position in the cylinder, usually, slightly before the piston has reached it maximum extension in the cylinder (referred to as BTDC - before top dead center). The solution is to try using a higher octane of gasoline as the higher octane slows the burning of the gasoline. If you are already using a 93 or 94 octane gasoline, take your vehicle to your friendly mechanic. As there may be other issues involved such as the incorrect timing of the engine.


What is that knocking noise coming from the engine?

If its gasoline it would be a problem in your head causing the piston to slap against the cylinder walls. If its a diesel engine then the knocking is caused by the .001 to .002 second delay between the fuel injector closing and the compression/combustion of the fuel

What is knocking and anti knocking agents?

Knocking in gas engines is when the fuel-air mixture in the cylinder self-ignites due to compression instead of waiting on the spark plug spark to ignite it. Anti-knocking agents are substances that let's the fuel-air mixture in the cylinder be compressed more w/o self-igniting.

If a Baja 180 is not running smooth and there is little power, it might be a dead cylinder. It is possible that a piston is broken which would cause the knocking sound and vibration.

What was the purpose of adding lead to gasoline?

Lead was added to gasoline to inexpensively increase octane ratings and to also help reduce engine knocking.Increasing octane and reduce engine knocking are exactly the same thing, as the test method to measure octane of a fuel is to see when a standard engine begins knocking. The higher compression ratio the standard test engine can be operated at without knocking, the higher the octane of the fuel being tested.

Why is your 99 jeep grand Cherokee engine knocking It stops knocking when I disconnect 6 injector connector.?

"knocking" is very broad so just a wild guess here. I think the reason the knocking stops when you disconnect the number 6 injector is; you are creating a "floating piston". In other words, this piston and cylinder are no longer producing power, they are no longer under a load, and they are no longer compressing the fuel that you have prevented from being injected into the cylinder. So, if you have something wrong with that cylinder, such as a bad piston, piston pin, connecting rod, rod bearing, etc., you have relieved the pressure which will quiet the knock. Again, just a wild guess!

What damage is done if I accidentally put 87 octane instead of 91 octane into my 03 Aviator?

There most likely will not be any long-term damage. On this tank of gas, you may experience "knocking" or "pinging" in the engine, meaning that the gasoline may ignite prematurely in the cylinder. If the knocking is severe and/or continues for a long time, it could cause engine damage. On the other hand, if the engine runs just fine on the lower-octane fuel, then there's no problem at all.


Where is the carbuerator on a 1997 Nissan Sentra?

The 1997 Nissan Sentra, like almost all passenger vehicles made since the late 1980s, does not use a carburetor. It uses fuel injection. Instead of mixing air and gasoline in the carburetor, then forcing that into the cylinder, the air is forced into the cylinder by itself, then gasoline is squirted into the cylinder by the fuel injector. There is one injector for each cylinder, and they are fed gasoline through a "fuel rail", which is a tube where gasoline is pumped from the gas tank to the engine, across all of the injectors, and back to the gas tank.
